The 59K HQ Comcast Combo Could Unlock Your Email, Bank, and More

In December 2024, a combolist file titled "59K HQ COMCAST COMBO hqhotmailcomboowner" was uploaded to a Telegram channel that trades stolen login credentials. HEROIC analysts confirmed 58,182 records in the file, each containing an email address, a plaintext password, and the URL the credentials were tied to. The file's name references Comcast and Hotmail account holders, suggesting whoever compiled it organized the list around those two providers.

Why This Is Dangerous

Because the passwords in this file are stored in plaintext and each record includes the exact URL the login was used on, attackers get a ready-made target list. They don't need to guess which service a stolen password unlocks, the URL tells them directly, which makes automated login attempts against email and internet service provider accounts faster and more effective.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs tied to each set of credentials

Why This Matters

An email account is rarely just an email account. It's usually the recovery address for banking apps, social media, and shopping accounts, so once an attacker gets into someone's Comcast or Hotmail inbox using a leaked password, they can often use the "forgot password" option elsewhere to chain their way into that person's bank, social media, and shopping accounts one after another. A single leaked credential can unlock far more than the original account it belonged to.

How a Combolist Like the 59K HQ Comcast Combo Gets Built

Combolists like this one aren't the result of a single hack against Comcast or Hotmail. They're usually assembled by pulling email and password pairs from older breaches and stealer malware infections, then sorting them by the email provider or service they belong to before packaging and sharing them on Telegram. Grouping records by provider, as this file's name suggests, makes the list more valuable to buyers who specifically want to target Comcast or Hotmail users.

Check If You Are Affected

If you use a Comcast or Hotmail email address, it's worth checking whether your credentials appear in this leak or any other. Run a free scan with HEROIC's breach checker, which searches more than 400 billion leaked records, and if you find a match, change that password immediately and update it anywhere else you may have reused it.
